9 Claims. I

This invention relates to gas burners formed from two similar, orsubstantially similar, sheet metal parts. More particularly, theinvention deals with burners, wherein the chamber or casing portion ofthe burner terminates in an outwardly extending peripheral flange, theflange being corrugated angularly to the edge of the flange so as toform, on the resulting burner, angular discharge nozzles. Still moreparticularly, the invention deals with burners of the characterdescribed, wherein the arrangement of one burner part on top of thecompanion burner part, in securing said parts together, will disposeadjacent discharge nozzles in different angular relationship to eachother.

The novel feature of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

Fig. 1 is a plan view of a part of one form of burner which I employwith part of the construction broken away in illustrating opposedangular relationship of the discharge nozzles of the burner.

Fig. 4 is a diagrammatic plan view of a modifled form of burner which Iemploy with part of the construction broken away.

Fig. 6 is a plan view of another form of burner which I employ, withpart of the construction broken away.

In gas burners of various types and kinds, it has been customary toprovide a cast burner with a series of discharge ports, or nozzles,spaced along peripheral edge portions thereof, or to form dischargenozzles between two sheet metal parts, usually of difierentconstruction, wherein the discharge nozzles are disposed at right anglesto the peripheral edge of the burner.

The purpose of my invention is to provide a burner of the characterdescribed, which is formed from two similar sheet metal stampings and,in some cases, one of the stampings is modified solely for theattachment of the gas supply tube but, more particularly, my inventiondeals with the arrangement of the discharge nozzle passages on theflanges of the burner parts, so

as to be disposed angularly thereon. Thus, in arranging two similarburner parts one upon the other and securing the same together,discharge nozzles disposed angularly to each other will be arrangedalong the peripheral edge of the burner, so that adjacent flames willextend angularly to each other and, at the same time, be sub-divided to,at least, a slight extent to insure complete ignition of all of thenozzles and produce a continuous flame throughout the periphery of theburner.

In Figs. 1 to 3, inclusive, I have shown one adaptation of my invention,wherein the burner I0 is in the form of an elongated central tubularbody I I, having an admission end it for introduction of the gas and arounded closed end [3. Along the sides of the body II are laterallydirected and opposed tubular extensions l4, having rounded ends, as atIS. The extensions 14 join the body H in rounded wall portions, as atIS. The complete burner is formed from two similar sheet metal parts ll,ll, these parts having peripheral flanges l8, l8 and the flanges arecorrugated angularly to the edges of the flanges, particularly on thestraight wall portions of the extensions M, as illustrated in Fig. 1 ofthe drawing and shown in detail in Fig. 3. The corrugations form offsetwalls l9, 19 which, in conjunction with opposed abutting walls, 29', 20form the gas discharge nozzles or passages 21, 2|. The portions of thewalls 20, 20 which overlap between the nozzles Zl, 2| can be welded orotherwise secured together. At the outer edges of the flanges, thesewalls abut, as indicated at 22 in Fig. 3 to subdivide adjacent nozzles2|, 2| one from the other.

By an angular arrangement of the corrugations in the mannerdiagrammatically indicated in Fig. 1 of the drawing, the reversing ofthe two similar parts ll, ll one upon the other will reverse theangularity of the nozzles. In other words, in one part, all of theflames will be directed in one common direction as, for example, thedirection of the full line arrow 23 of Fig. 1; whereas in the otherpart, the flame will be directed in the direction of the dotted arrow 24of said figure. Where the corrugations extend through the roundedportions of the flanges, a somewhat wider spacing between the dischargenozzles will prevail but these discharges will be sufficiently close tofacilitate complete ignition of the burner from any one position byextension of the flame in ribbon-like fashion around the flanges.

In this connection, it will be understood that the particular size andangularity of the corrugations forming the resulting nozzles 2!, 21' canbe varied, depending upon the size and dimensions of the burner and theillustration in the accompanying drawing is simply a diagrammaticillustration.

In Fig. 4 of the drawing, I have diagrammatically shown a slightmodification of the structure shown in Fig. 1 which would amount to asection of the burner shown in Fig. 1, including two of the extensionsl4 and dispensing with the ends l2 and I3. In other words, asubstantially H-type burner 25 is employed, wherein the two parts 26, 26are identical, except from the standpoint that the part 26 is apertured,as seen at 21, for the reception of a fuel admission pipe forintroducing gas into the burner.

In Fig. 4, the tubular extensions 23 are substantially identical withthe extensions [4 of Fig. 1 and these tubular extensions are united in acentral tubular portion 29. The peripheral flanges 30 will becorrugated, as with the structure shown in Fig. 1, to produce thedistribution of nozzles, the same as in Fig. l. The type of burner,shown in Fig. 4, is suitable for use in small ranges, or two of suchburners could be used in a range; Whereas, with the structure shown inFig. 1, a single burner can be utilized to heat the range compartment ofa gas stove.

In Fig. 5 of the drawing, I have shown a modified form of burner whichis in the form of a single elongated tubular body 3|, having an admission end 32 and a closed end 33, the body having, throughout themajor portion of its length, a peripheral flange 34. burner is formedfrom two similar parts 35, 35', having the flanges corrugated angularlyto provide the nozzle discharges 36, 36. Again, as with the constructionshown in the other figures, the formation of a single sheet metalstamping is utilized to produce the resulting burner. It is preferredthat the sheet metal employed be of a type and kind that will withstandthe tempera.- ture and such material as stainless steel is suitable forthis purpose.

In Fig. 6 of the drawing, I have shown my invention as applied to theconstruction of a round ring-type burner, such as generally used on thetop of gas stoves for the heating of pots and pans in the preparation offood. Here again,

the burner is formed from two similar sheet metal parts 31, 31', thepart 3'! being modified only to the extent of having an aperture 38therein for reception of a gas supply pipe.

The burner shown in Fig. 6 has a ring-type tubular casing 39, having aninwardly extending flange portion 4!], 4B and an outwardly extendingflange portion 4 l, 4 I These flange portions are corrugated to form thedischarge nozzles 42, d2 angularly disposed to each other, as with theconstruction shown in the other figures. The only difierence in Fig. 6of the drawing is that, instead of simply placing one sheet metalstamping directly upon the top of the other to form the resultingburner, the one stamping is rotated to a slight extent in thisinversion, as will clearly appear from a consideration. of Fig. 6, thepurpose here being to provide a distribution of the nozzles through theentire periphery of the burner so as to distribute the flame and toinsure complete ignition of the entire flame in carrying from one nozzleto the other. Here again, it will be understood that the illustration inFig. 6 is diagrammatic in illustrating an adaptation of the inventionand the size of the Here again, the

corrugations and angularly thereof can be varied to produce the mostdesirable results in the finished burner.

Considering Fig. 1 of the drawing, it will be apparent that sufilcientspacing is provided between the extensions 14 to facilitate eflicientoperation of the burner and this spacing also will be practical from astandpoint of producing the sheet metal stampings with a minimum ofwaste by the possibility of nesting the projections or extensions [4 ofone sheet with respect to those of an adjacent sheet.
